Workout: Threshold Eights. Type: Intervals. Eight rounds of two minutes at threshold on the rower, one minute easy. Threshold is hard-but-repeatable, the pace you could just about hold for an hour if you had to. Every interval should be the same distance; if your last one drops off a cliff, you started too hot. The score is total distance in the work intervals. 1 movement across 1 section. Created by Fiz.
